Abstract: | Inspired by a theorem of Marcinkiewicz J. Marcinkiewicz, On a class of functions and their Fourier series, C. R. Soc. Sci. Varsovie, 26:71–77, 1934. Reprinted in: J. Marcinkiewicz, Collected Papers (A. Zygmund (Ed.)), PaństwoweWydawnictwo Naukowe,Warsaw, 1964] stating that the maximum of the absolute values of real Fourier
coefficients a
n
and b
n
of a function of bounded p-variation
( p \geqslant 1 ) \left( {p \geqslant 1} \right) on an interval 0, 1] is of order O(n
−1/p
) as n → ∞, we compute the Fourier coefficients of the linear fractional stable motion (LFSM) and of the closely related Riemann–Liouville
(RL) process and investigate the rate of their decay. |
